To all whom, t may concern.:

Beit known that-1, JOHN S. HINEs, a citi-f zen of the United States,residing in the city of Portland, inthe county'of Jay and State ofIndiana,'have invented a new and useful Construction for Derricks andMeansfor Raising Them into Position, which invention I denominate asectional derrick, of whichv the following .is a fullI and comprehensivespecification and eX osition, being such as kled in the art to which itap ertains to make and ,use the .same with abso ute exactitude. n

My invention relates to sectional derricks designed more particularlyfor usein connection with dee well.drilling, same to forma part of what1s known in the vernacular o the trade as a standard rig.

The object ofthis my present invention,-

broadl speaking, is the rovisionof an improve construction of t e classstateddesigned to give a maximum of mechanical efIiciency with a minimumof expense and in which the item of maintenance will be practi- Morespecically stated, my object is to provide a derrick formed, preferably,entirely of metal and which is composed of va plurality of sections ofupwardly-decreasing dimensions, the sections being capable of beingeasily collapsed or folded into a com act space and when assemple'dtogether to orm a rigid practically indestructible and ornate structureand at the same time being economicall eflicient and forming a standardderrick oth in eiiiciency and general` ap- .,pearances, and, nally,other'obJects are to provide a derrick which may be easily assembled anddisassembled,' easily transportare shown most clearly in the accompanyinseven sheets of-drawings, yformingl a part o this specification, v inwhich- Figure-1 shows a side elevation of the first or lower section 1nposition,'also the second j Specification of Letters Patent.Applimionmed December 3.1906. serial No. 846,069.

.Fig 16 shows one o f the `sections folded.

Similar indices denote andrefer to like arts throughoutthe severalAviews of the awmgs. j In order tov render the construction andloperation of my invention still more facile, .I nowtakeu a detaildescription thereof in which I will escribe the construction andA theoperation thereof as briefly and as compactlyas I may.

My invention comprisesa pluralit of separable sections divided from eachot er horilzontally and constructed convergentl upf'. wardly, eachsection bemg substantia y of. same dimensions atits base asis the nextlower section thereto at its apex- In this instance Iprovide fourdlstinct sections, designated, for convenience of description, yl'etftersA, B, C, and D, counting from the lower section upwardly.)

Said posts are formed of angle-iron in order to give them the desiredstrength with a minimum of height. Said posts are connected at theirlower end portions by the four lower end ties, (designated by thenumerals 5, 6, 7, and' 8.) At their upper ends said posts are connectedby the four upper end ties 9, 10,l 11, and 12, the latter set of tiesbeing shorter than the former in order to give the propershape to thesection. Near their centers said posts are again connected by the fourhorizontal ties, (designated by the numerals 13, 14, 15, and 16,) whichare parallel with the aforesaid ties. Extending between the posts 1 and2 and located between the ties 9 and 13 are the crossing braces 17 and18. Extending between the posts 2 and 3 and located between the ties 10and 14 are the crossing-braces 19 and 20. Extending between the posts 3and 4 and located between the ties lland are the crossing braces 21 and22, and extending ybetween the posts 4 and 1 and located between theties 12 ,and 16 are the crossing braces 23 and 24.

All of said ties should be formed of angleiron, as shown. All of thevarious parts of 'Section A are detachably secured together by bolts, asshown, thereby completing the framework of this section, as shown inFigs. 1, 2, 3, 4, 5, 6, 9, and 12. l

Accessory parts of section A.-Secured to the rear faces and extendingslightly above the upper endsv of the posts 4 and 1 are hinge members 25rand 26, respectively. (For, detail of hinges see Fig. 19.)Extending'between the -ties 8 and 16 are the vertical hanger-posts 27and 28 which carry revolubly the bull-wheel reel, which is com osed ofthe spindle 29 and the two bull-Whee s 30 and 31. Said reel may beoperated in any well-known manner either by power or by hand, and it isada ted to rotate in either direction. Exten ing back from the'tie 8parallel with the ties 5 and 7 and between the wheels30 and 31 are theanglc-iron track-bars 32 and 33,. Extending downward and rearwardly atan angle from the tie 12 and connected toand ,alined with the track-bars32 and 33, res ectively, are the track-bars 34 and 35, wliich 4are forpurploses hereinafter stated. Extending up t e front side of SectionAfrom the center of the tie 6 to the center of the tie 10 is theladder-section 36. t l f Section B.-The numerals 101, 102, 103, and104designate the four cornerposts of thisl section, which posts aresubstantially the same length and of same size and formed in same mannerasthe posts of Section A. Said lposts of Section Bare connected togetherat their lower ends by the four lower end ties 105, 106, 107, and 108,and at their upper ends said posts are connected by the four upper endties 109, 110, 111, and 112, this latter set of the former, butsuiiicient' to give the same vconverging inclination to Section B as isgiven to said Section A, all substantially as shown in the drawings.'Ihis Section B is made folding or collapsible, as shown in Fig. 16, andthe means for accomplishing this feature I will now describe, and as theeon.`

struction thereof is the .same` between each two of the fourcorner-posts I will now de scribe the rear side, as shown in Figs. 5 and15, and the same description will apply to the o ther three sides ofthis section. 1

Folding means-Connecting the posts 104 and 101 near their centers. isthe two-part tie 113, the members of which overlap each other in thecenter, where theyy are held togetherbyaninverted-U-shapedclip,(denominated by the numeral 114.) Passing centies being shorter than ytrally through the sides of the clip 114 and extending across the spacebetween the sides thereof is an eyelet 115, (shown in Fig. 20,) therebeing an a erture through the end portion of the mem ersof the tie 113,bywhich said members are pivotally mounted on said eyelet.` The numerals116 and 117 denote two contacting vertical bars :located parallel witheach other. To the upper end of the bar,116 are pivoted the inneroverlapping ends lof the downwardly and inwardly extendin arms 118 119,and to the lower end of the ar 117 is pivoted the inner overlapping endsof the upwardlyand inwardly extending arms 120 121. The' outer ends ofsaid arms 118 119' and 120 121 'are pivotally secured to thecorner-posts 104'and101, as indicated. Slidably mounted around the lowerportion of the bar 1161s awinged clip 122, and in like manner mountedaround the upper ortion of the bar 117 is a'winged clip 128. ivoted tothe wings of the winged clip 122 are the inner ends of the arms 124 and125, with their outer diverging ends pivoted to the respective' posts104 and 101 by same bolts which secure the ends of the tie l113 to saidposts. -Pivoted to the wings of the winged clip 123 are the inner endsof the larms 1,26 and 127, with their outer ends pivoted to therespecros tive posts 104 and 101 by same bolts which secure the ends ofthe tie 113 to said osts. The numeral 131 denotes a band-clip shdableover'and slidably co tacting the two bars 1 16 and 117. When op ,ned outin its assembled position, as Fig. 7, I insert a,bolt 128 throughcorresponding apertures 'therefor in the center of the winged clip 122and through corresponding apertures in the bars 116 and 117. Also a bolt129 is inserted. through corresponding apertures thereforin the wingedclip 123 andthe bars 116 and 117', and the bolt 130 is inserted throughcorresponding ISO apertures therefor in the bars 116 and 1 17 and throu-h the eye of said eyelet 115, and therefore t ough the membersof ,thetie 113. The operation of said parts is as follows: The device beingright end upward, as in Fig. 7, but partially dismantled, as in Fig. 15,it

will be apparent that if the clip 1 14 be pressed upward then the posts104 and 101 may be brought toward each other, in which movement the bar116will slide forward in the winged clip 122, and the bar 1 17 willslide upward in the winged clip 123,- the arms 118 and 119 foldingtogether and the arms 120 v and 121 folding together, all of said armsfinally coming parallel with thpsts 104 and i 101, and allof said partsbeing inclosed withil? the angles of the posts 104 and`101, .as in 16.

heuabove-describ'ed folding means is identically the same between theposts 101 and 102, 102' and 103, 103 and 104, same as it is -between theposts 104 and 101, and therefore a description of said parts is notnecessary, as the constructionv is shown most clearly in the drawings. v

If now-Section B is constructed asj'ust de-A scribed, the sectionbeingassembled as shown in Figs. 2, 7, 8, and 12, whichA to ether showall four sides of this Section B ,y an the section may be collapsed byfirst removing the lower ties 105, 106, 107, and 108 and the upper ties109, 110, 111,. and 112, then removm the bolts 128, 129, and 130 fromthe four si es of the section. After the above the four posts 101, 102,103, and 104 may be brou ht'together as in Fig. 16, with all of saidolding means contained in the space formed by the an les of said posts.

t is not to" be understood that I limit myself to the specific form offolding y,means above described, as it is apparent that other means maybe employed for same purpose. Detaehably secured on the rear side `ofSection B are the two track-bars 132 and .133, adapted to unite and bealined with the trackbars'34 and 35 of Section A.

The numeral 134 denotes the ladder-secjtion for the` Section B, whichextends centrallyup the front of Section B and is alined with theladder-section 36 of Section A.

" Secured to the rear face of and extending slightly below the lowerends of the posts A104 and 101 are the hinge'members 135 and 136,

` respectively, which are adapted to be pivot- 6""are shown-.clearly inFigs. 2, 5,6, Y13, and 14.

ally seeuredin contact with said hinge members 25` and 26, respectively,of Section A. Also secured tothe rear faces of and extending slightlyabove the upper ends of theposts 104 and 101 are the hin e members 137and 138, respectively, whie will presently be further referred to inconnection with Sec- Section (l-The four sides -of this sectionSection() comprises inits construction the and "308. The upp fourcomer-posts 201, 202,203, and 204, which rise. eonvergently upward, asshown in said views of the drawings. Said posts are of substantially thesame length and of same form and construction'as are the correspondingposts of said Sections A and B. 'Said posts of Section C are connectedtogether detachably at their loweryends by the four lower end ties 205-,206,207, and 208, and at their upper ends said posts are'connect'eddetachably by the four upper end ties 209, 210,

211, and 212, this'latter set of ties of courseY .being shorter than theformer, whereby said posts will incline inwardly at same inclinai tionas do thecorresponding'posts of lSections A and B therebelow. The,folding means for Section C is in every essential particular likethefolding means described in rel 4 lation to Section B, andtherefore arepetition tions 135 and 136, respectively, of Section B.

Also secured to the rear faces of and-extending slightly above the 'pperends of the posts 204 and 201 are the hi ge members 237 and 238,respectively, which will .presently be further referred to in connectionwith Section. D.

Section D.-The four sides of Section D are shown in Figs. 12, 9, 10,-and 11. .This section includes in its framework vthe four cornerposts301, 302, 303, and 304, which rise convergently upward, as shown in thedrawings. `Said posts are of substantially the same length and of sameform and construction as are the corresponding posts` of Sections A, B,and C. Said posts of this Section D are'detachably Aconnected togetherat their lower end by the four lower end ties305, 306, 307,-

er ends of said postsl are detachably -connected by the four upper endties 309, 310, 311, and 312. This latter set of ties are shorter thantheformerin order to give said posts the same inclination as thecorresponding posts of Sections A, B, and C. The folding means of-Sectionl D yis in everyr essential particul-ar like the folding meansdescribed in relation to Section B, and therefore a repetition ofthedescri tion thereof is "not necessary, as it would a d nothing toelearness of comprehension, as the description of one can betaken as thedescriptionof the other, the parts being shown in thedrawelhe numeral334 denotes the ladderection ofSection D. Said -ladder extends up thefront of this section and is alined with the ladder-section of SectionsA, B, and C, as shown in Fig. 12.l

Secured to the rear faces of the lower ends of the posts 304 and 301 andextending slightly above the ends thereof are the hingeA be turned upand down, as in Fig. 12, in order the side of the derrick, through whicha drill-q i oo to provide a comparatively large opening 1n stem (notshown) may be taken within the inclosure of the derrick.

(jenemlities-Section A is adapted to rest on the ground or on mudsillsor in any otherV manner as may be deemed advisable. Section B is adaptedto rest on Section A. Secltion C is adapted to rest on Section B, and

Section Dis adapted to rest on Section C, all as shownv in Fig. 12. Thecorner-posts of each of the sections above Section A are adapted to reston the corresponding cornerposts of the section next below. Thecorner-posts 1, 101, 201, and 301 are ada ted to be detachably securedtogether byl olts or the like, as indicated in the drawings. In likemanner the posts 2, 1-02, 202, and 302 are secured together, and in,like manner the posts 3, 103, 203, and 303 are secured togetlier, asare also the posts 4, 104, 204, and 304. The lower end of each of saidposts above'SectionA has secured to it a downwardly-extending fiange orreinforcing-shoel .which extends down over the upwardly-projectingportion of the post next below With corresponding apertures to receiveretainingbolts, as indicated in some of the views. Said flanges alsoserve to retain the abutting ends of the posts in alinement with eachother andto break the ioints between the posts. In this construction allpartsof each of the sections is made entirely of metal, as has beenintimated'.

Iwould call attention to the fact that the ladder-sections whenassembled extend from the base to the a ex of thederrick, 'as shown in Fig; 12, each adder-section being removably connected tocitsderrick-section. The track formed by the track-bars extends from somedistance in the rear of the derrick only to the top of SectionB, saidtrack being for the purpose which will resently. be explained. Theworking too s for manipulating a well may be sus ended insidethe'derrick from the top of ection Din any wellknown manner.

The numeral 400v denotes a truck having supporting-wheels mounted `onthe ends of an L-shaped or angle-iron axle, with a tongue extendingcentrally out from said axle and secured by suitable braces, allsubstantially as shown in perspective in Fig. 17. 7o

Numeral 401 designates a'pulley-block containing two pulley-wheelsarranged tandem, with their concave faces opposite to and almost incontact with each other. Said pulley-block 401 is provided with a hookat one end, whereby it may be hooked into an aperture therefor locatedin the center of the ties 10, 110, and 210, where said pulley willoccupy the positlons indicated in Figs. 1,2, 5, and 9.

The numeral 402 refers to a single pulleyblock which is provided withl ahook at one end, whereby it may be attached in an aperture thereforlocated in the centers of the ties 112 and 212, as indicated in Figs. 2,5, 854

6, and 9.

The numeral 403 designates a lever formed of channel-iron or the like,adapted to be detachably secured to the ladder-sections of the SectionsB, C, and D and to extend a con- 9o siderable distance therebelow, orrather to extend upward when said sections are nverted, and said leveris shown in Figs. 1, 2, 5, 6, and 9. Extending out at right angles fromthe outer end of the lever 1s an eye- 9 5 piece 403a for the purposeresently appearlng, and located a short istance from the end of .thelever and from said eyepiece is a second eyepiece 403 forV the purposepresentl appearing.

T e numeral 404 denotes a cable or the like adapted to be wound on thespindle 29, extending from thence through the .pulleyblock 401 andprovided on-i ts outer end with a hook to engage in either of saideyepieces of the lever 403, as is shown in the drawings.' The numeral405 denotesl a cable or the like adaptedto be Wound on the spindle 29,extending from thence through the pulleyblock 402, and provided on itsouter end with'v a hook to engage in an aperture formed in the outer endportion of the tongue of the truck 400, as shown in Figs. 2, 5, 6,and'9.

Operation of ositioning the sections.-As before indicated Section A isassembled in the position where it is to be employed. The other sectionsare ,to be erected'up end down to the rear of and near Section A.Forexample, Section B is erected on the track 32 '33 with its rear sidenext the rear side of Section A, after which the lever 403 is attachedThen the spindle 29 is revolved to Vwind thereon and tighten the cable404 sufficient to tip Section B andbring its hinge members 137 138 inalinement and contact with thehinge IOO lus

members 25 26 of Section A, and at this time bolts are inserted to joinsaid hinge members, thereby forming a complete 4hinge of the 'members 26and 136 and another hinge of the member 25 and 135. After said hingesare formed, as stated, then the spindle 29 is eventuate in loweringSection B down gradu' ally into the position itl should occupy, as shownin Fig. 2. VAfter Section B is positioned as above stated then themeeting ends of all of the corner-posts of Sections A and B are boltedtogether, as stated. The remaining sections to be positioned are raisedas follows: Referring now to Fig. 2, the truck 400 is now laced on thetrack which extends back from Section A, with the tongue thereofextending upward, as shown. Section C being now assembled'and inverted,its rear upper end is rested inthe channel of the axle of said truck andthe u per point of the tongue of the truck is plhced inside-that is,against lthe inner face of the tie 208, for which a notch may beprovided, as is shown in Fig. 18. The cable 405 is now extended upwardfrom the spindle 29 through the pulley-block` 402, and the hook on theouter end of said cable is attached in the aperture 400a in the outerportion of the tongue of the truck. N ow if the spindle 29 be revolvedit is manifest that Section C will be elevated, being carried on thetruckthe. wheels of the truck traveling up the tracks until the hingemembers 235 and .236 are alined and contacted with .the respective hingemembers 137 and 138 of Section B.

Pivot-bolts are theni nsertedto join said respective pairs ofhinge'members, and thereby complete the hinges, as in Fig. 5. After theabove the cable 404 is brought into play, the hook of said cable beingattached in the eyepiece 403", as in Fig. 5, and the lower portion ofthe cable 404 is attached on the spindle 29 and adapted to be woundthereon, reversely from the winding thereon of the cable 405.

Now at this point the spindle 29 is revolved oppositely to its lastrotation, to wind thereon the cable .404, which of course will unwindthe cable 405, which will eventuate in turning Section C on its hinges',as shown in Fig. 5, and simultaneouslywith the turning and raising ofSection C the truck Will belowered-that is, it will travel down thetrack, Section C coming to its upright position synchronously with thetruck, reaching the horizontal ortion of the track ready' for a newload. he lower ends of the postsof Section C are now secured to theupper ends of the osts of Section B, as indicated in Fig. 6.y

he cables areA now unwound from the spindle 29 and the pulley-blocks401,and 402 are moved up tothe top of Section C,vbeing secured in samemanner as before to correspondin parts of the last-named section.Section is now placed on the truck, as in Fig. 6, the lcable 405 beingthen attached as before, and Section D is raised, and its hinge members335 and 336 are pivotally connected to the hinge members 237 and 238, asin Fig. 9, and the Section D is then raised and the truck lowered insaine manner as before stated in relation Aof Section-C, after which thelower ends of the osts of Section D are secured to the upper ens of theposts of Section C, which will complete the derrick ready for itsemployment in the usual manner. After the derrick has been assembled asabove set forth thenthe pulleys 401 and 402 may be removed. Also thelever 403 is removed, and, ifdesired, the said cables maybe removed, orthey'may be employed for other purposes, all to again be brought intoemployment in dismembering the derrick.

Dtsmembering-Desirin now to dismantle and remove the derric the reverseo eration is taken in lowering the sections, tffe only dierence beingthat the hook on the cable 404 is to be attached in the eye ieee 403a inplace of the eyepiece 403", the o ject in this being to top the sectioneither forward lor backwardbeyond the point of balance or equipoise,(seeFig. 1,) depending on Whether the section is being posltioned orremoved, respectively. After all the sections have been'l taken downfrom pyramidal contact they-are each (except Section A) collapsed andfolded, as shown in Figs. 15 and 16. It is intended that Section Ashould be entirely dismembered, after which all of the parts may beloaded in a small compass of space and trans orted to a new location. i

While have shown and described the best means to me known at this timefor carryin out the objects of my invention in a practica manner, Idesire to have it distinctlyvunderstood that, I do not restrict myselfto the exact detailsl of construction shown and described, but hold thatany changes or variations therein as would suggest themselves to anordinary mechanic would clearly fall within thelimits and scope of myinvention.

The terms upward downward, horizontal, verticah and other similar `termsare used for convenience of descri tion, and it is not intended by theuse of suc terms to limit my invention to the relative positionsindicated thereby.
